[5] Co-written by Mann, "Home for a Rest" is a popular drinking song in Canada; it has been called "legendary" and the "ultimate Canadian frosh-week/wedding-reception anthem" by Marsha Lederman of The Globe and Mail,[2][8] an "iconic drinking song" by Alex Cooper of the Revelstoke Times Review,[9] and "Canada’s unofficial national anthem" by Patricia D'Cunha of CityNews.

[14][15][16] The Waiting Room deals with the topic of Mann's battle with colorectal cancer, and was adapted into a theatrical work by Morris Panych which was produced by Vancouver's Arts Club Theatre Company in 2015.

[1][2] In addition to Spirit of the West and his solo albums, Mann appeared as a guest musician on recordings by Mae Moore, The Waltons, James Keelaghan and Paul Hyde.

[19] Mann went on to appear on several television shows as a guest actor, including Cold Squad, Dark Angel, Stargate SG-1, Battlestar Galactica, Smallville and Da Vinci's Inquest.

[21] In the film he portrayed the character Slade Craven—a goth rocker reminiscent of Marilyn Manson who stages a concert in a 747—and Simon Flanders—a passenger of the flight who is a Satanic fan planning to crash the plane in Eastern Kansas while disguised as Craven.

[25] Prior to marrying Daum, he was romantically linked with Jean Smith of the band Mecca Normal, who was revealed in the 2001 book Have Not Been the Same: The Can-Rock Renaissance 1985-1995 as the inspiration behind one of Spirit of the West's best-known hit singles, "Political".

Mann wrote a few solo songs following his diagnosis, including one for Spirit Unforgettable[33] and two for Daum's Alzheimer-related theatrical play Forget About Tomorrow.

[35] A similar show in 2019 included Greaves, Maize, Finlayson, Doyle, Kane, Royal Wood, Andrew Cash, Jim Cuddy, Dayna Manning and Chris Tait.

In 2017, friends and colleagues organized a similar concert in Vancouver on November 19 at the Commodore Ballroom, with a lineup including Spirit of the West, Odds, Barney Bentall, Dustin Bentall, Jim Byrnes, Kendel Carson, Jim Cuddy, Alan Doyle, Colin James, Sarah McLachlan, Ed Robertson, Shari Ulrich and Spirit: The Next Generation, an act consisting of the band members' children.

[36] Before the Vancouver show, the performing musicians participated in a group recording of the band's signature song "Home for a Rest" as a tribute to Mann.

[37] In 2018, Vancouver's Off the Rail Brewing Company introduced The Spirit Lifter, a limited edition pilsner, to raise funds for Mann's medical costs.
